Heavy Chaingun Barrel: by Child_Killer

In this tutorial we will be adding a new barrel, called the "Heavy Chaingun Barrel"



Step #1
Create a file in the scripts/turrets/ folder, name it chaingunBarrelLarge and paste this in:

// Tip for players: 2-3 of these can chew up light to medium armors in an instant.
//--------------------------------------------------------------------------

Step #2
Now, make a file in the scripts/packs folder, name this one chaingunbarrel, 
and then paste this in:

//--------------------------------------------------------------------------
//
// Chaingun barrel pack
//
//--------------------------------------------------------------------------

datablock ShapeBaseImageData(ChaingunBarrelPackImage)
{
mass = 15;

shapeFile = "pack_barrel_fusion.dts";
item = ChaingunBarrelPack;
mountPoint = 1;
offset = "0 0 0";
turretBarrel = "ChaingunBarrelLarge";

stateName[0] = "Idle";
stateTransitionOnTriggerDown[0] = "Activate";

stateName[1] = "Activate";
stateScript[1] = "onActivate";
stateTransitionOnTriggerUp[1] = "Deactivate";

stateName[2] = "Deactivate";
stateScript[2] = "onDeactivate";
stateTransitionOnTimeOut[2] = "Idle";

isLarge = true;
};

datablock ItemData(ChaingunBarrelPack)
{
className = Pack;
catagory = "Packs";
shapeFile = "pack_barrel_fusion.dts";
mass = 1;
elasticity = 0.2;
friction = 0.6;
pickupRadius = 2;
rotate = true;
image = "ChaingunBarrelPackImage";
pickUpName = "a heavy chaingun barrel pack";

computeCRC = true;

};

function ChaingunBarrelPackImage::onActivate(%data, %obj, %slot)
{
checkTurretMount(%data, %obj, %slot); // This cheks if there is a turret where the player is aiming.
}

function ChaingunBarrelPackImage::onDeactivate(%data, %obj, %slot)
{
%obj.setImageTrigger($BackpackSlot, false);
}

function ChaingunBarrelPack::onPickup(%this, %obj, %shape, %amount)
{
// created to prevent console errors
}







Step #3
Open up hud.cs, find where it says:
//----------------------------------------------------------------------------
// Backpack Hud
//----------------------------------------------------------------------------
Add this:
$BackpackHudData[18, itemDataName] = "ChaingunBarrelPack";
$BackpackHudData[18, bitmapName] = "gui/hud_new_packturret.png";

And don`t forget to increase the BackpackHudCount by one.





Step #4
Open inventoryHud.cs
As usual, you`ll have to find out where to put the code for yourself.
Two pieces of code:
First piece:
$NameToInv["Heavy Chaingun Barrel"] = "ChaingunBarrelPack";

Second piece:
$InvPack[27] = "Heavy Chaingun Barrel";




Step #5
At the very bottom in pack.cs, add this:
exec("scripts/packs/chaingunbarrel.cs");




Step #6
At the very bottom of turret.cs, add this:
exec("scripts/turrets/chaingunBarrelLarge.cs");






Step #7
Open up player.cs, and add this to you-know-where.
max [ChaingunBarrelPack] = 1;
